The more I hear of the NZ system, the more I like first past the post!!! why should the greens be effectively GIVEN seats when they couldn't win any in their own right?  IN minority govts which is what this system virtually ensures, someone or a few people ends up with an effective balance on power and is ALWAYS the result of a very small vote. Democracy after all is the rule of the majority and these systems seem determined to disenfranchise the majority to favour the minority.
